Big laptop>><<

Dad just got a mini laptop to his work, and the thing is, it has no hard disk or whatever the word is, where u put the CD! nd i have my old lap..they both HP..is there any way i can network them, like if i wanna share files btwen them? any ideas on how to do so...??

CDs go into CD-ROMs. Hard to believe laptop does not have it, must be very old or very specific I suppose? Anyway, you can use USB drive ("flash") to transfer data or you could connect them via LAN ports.

LAN: get a wire (in PC store) like this: . Both ends of the wire must look the same. Plug one end to 1 laptop (where you plug your Internet cable), another end to laptop 2. Hopefully automatic detection will sort it all out and you will be able to transfer files

generally speaking, a good option would be either a USB stick as explained above or an external hard drive. Using an external CD/DVD drive might be a good idea, as well.

As for the network cable, it doesn't work as simple as that
If you use a standard RJ-45 cable, you will not get any connectivity without putting a hub, router or switch between the two computers. A crossover cable should do the trick, though
